Does anyone know of any kind of transparency paper (for printing) that can be found in 11" x 17" or larger. I do not want digital transparency film, because it is not clear enough (because of the thick emulsion coatings), but something more along the lines of transparency overhead projection paper.
If anyone knows any companies that sell this please let me know!
Thanks!

If I were faced with that need, I would go to my local Staples and start asking questions. They have various abilities with large size printing. You may have a Kinko or other somesuch equivalent business. I do much product research on the internet but find talking with a human often triggers answers I didn't have questions for.
